Thus far I have experienced the following issues with my 2014 S550.
Two replace front ball joints (no lubrication; warranty)
New tires at 17K (all had inside belts exposed)
warped gas filler door (warranty)
Squeaky front seat (twice fixed under warranty)
New brake pads (warranty)
Recurring active ride control malfunctions (twice on warranty, still intermittent)

Aside from these, the car has been spectacular, and I love driving it. The massaging seats are worthless, but that is a small gripe. Otherwise the car rides magnificently. I do a fair amount of freeway driving and do appreciate the secure feeling I have in this car and the comfort it affords. Probably should have waited for more of the kinks to be worked out, but so be it.

 

whoh, what a killjoy


I have had brakes worked on, and have a squeak beginning to develop in my seat.....it is sort of annoying.......kind of like Grandpa's recliner


I guess I enjoy mine too........it's a bore to drive however and the exterior is pretty stale to me.......I also kind of agree about the massage seats, mediocre at best......but they do provide a slight amount of relief I guess at times......


funny thing I wish I could have gotten the quilted seats.......not offered in 2013 when I configured mine

 

Had ball joint replaced on my 2014 after about 2000 miles under warranty Dealer had to order part said they rarely go bad.
